Hey all I am installing a set of 113 vette heads on my TPI. I have a question, did GM use hardened pushrods on these motors with the guideplates? I can't seem to find anything that says that they did, all I can come up with is "Rods for late model roller L98" they come back to the same as the IROC 350 that didn't have guide plates........



Thanks

if it has guide plates it has hardened push rods, or at least it should have

 

Yeah Ede that was what I was thinking but did the IROC roller 350 have hardened ones with out plates they keep saying stock for stock they are the same as the vette. I can tell you one thing the push rods do not touch the plates.


Thanks
